Automatic Metadata about … me :-)

Based on no more than 17 events that I helped to organize, eventseer paints this picture of me:

Erik Duval has been associated with 17 events and shares similar interests with Wolfgang Nejdl, Martin Wolpers and Ralf Klamma. Erik’s main research interests are metadata, learning objects and education.

Pretty accurate, I think. And another illustration of how simple techniques can lead to quite correct results…

    Not even remotely accurate for me. Says I’m associated with three events.

    Not that accurate, it’s true. I think that the main reason is that it only detected your involvement in three events. Seems like it only tracks whether one was involved in organising an event, and for instance doesn’t track who spoke at an event – otherwise, the count would have been much higher for both of us :-).

    Raises the question of how one could indicate the trustworthiness of such metadata – a “this statement is not very reliable because it is based on less than 5 events” warning or something like that might help…

    Hi, I’m the lead developer of, so I figured I might add some details… 🙂 At the moment, the network and topic lists are based on conference calls and scientific publications. So, if you weren’t mentioned in the conference call but attended the conference to present a paper there’s still a chance we might have picked it up. There’s a lot of tuning to be done to the main algorithm in terms of weighting metadata in terms of e.g. the reliability of the mined data, the closeness of the relationship (you’re more likely to have something in common with a co-author than a fellow speaker at a conference), and so on.

    Having some kind of trustworthiness indicator is a very good idea!
